YBEF funded and guided this innovative asset-based Strategic Framework to support the Growing Ocean Observing Industry Cluster in Newport and Central Lincoln County. The Framework sets the stage for ocean observing as a ...

conservation and ecology. Currently, the most widely used methods for obtaining such estimates involve either sighting
animals from transect lines or some form of capture-recapture on marked or uniquely identifiable ind ...

Density estimation for marine mammal species is performed primarily using
visual distance sampling or capture-recapture. Minke whales in Hawaiian waters
are very difficult to sight; however, they produce a distinctive ...

Euphausia pacifica occupy a remarkably wide range of ecosystems. We examined the
differences in brood sizes from eight regions of the North Pacific to explore how variation
in the brood size might contribute to their s ...

We tested the potential of a selective flatfish trawl to reduce bycatch of slope rockfish in the upper continental slope bottom-trawl fishery (250–500 m) on the U.S. West Coast. The trawl we tested differed from typical ...

Various methods have been developed to mitigate the adverse effects of the Federal Columbia River Power System on juvenile Pacific salmon out-migrating through the Columbia River basin. In this study, we found that hatch ...

Rockfish species of the genus Sebastes are notable for being numerous and diverse. Rockfishes are unusual among fish because they fertilize their eggs internally and release live, swimming larvae. They undergo complex co ...

The underlying causes of mortality during critical life stages of fish are not well
understood, nor is it clear if these causes are similar for naturally versus artificially propagated (i.e.
hatchery) individuals. To a ...

Juvenile red hake Urophycis chuss were collected while they were inhabiting sea scallops Placopecten magellanicus , and the effects of appetite and food availability on prey consumption and growth were examined under lab ...

The food habits of the 2 dominant larval pleuronectids off the Oregon coast - English sole Parophrys vetulus and butter sole Isopsetta isolepis - were analysed. Most specimens were collected during January-April 1971 and ...

Filtration by adult Euphausia pacifica was measured before and during the upwelling season, using both “disappearance of chlorophyll” and “disappearance of cells” techniques. Results show that feeding rates and selectivi ...

Ocean fronts represent productive regions of the ocean, but predator-prey interactions within these features are
poorly understood partially due to the coarse-scale and biases of net-based sampling methods. We used the ...

Fisheries models often assume that discarded undersized fish and target species will survive and contribute to future recruitment and yield. If smaller fish are more susceptible to capture stressors than larger fish, the ...

An indirect fluorescent antibody test (IFAT) was developed for detection of the rickettsia that was causing epizootics among salmonids cultured in seawater net-pens in southern Chile. Antiserum against the rickettsial ag ...

The output of gas and tephra from volcanoes is an inherently disorganized process that makes reliable flux estimates challenging to obtain. Continuous monitoring of gas flux has been achieved in only a few instances at s ...

The effects of reduced food availability on the behavior of juvenile walleye pollock Theragra chalcogramma were examined in laboratory experiments designed to test for potential energy-conserving responses. Groups of juv ...

In ocean fisheries for Pacific salmon Oncorhynchus spp., there can be several forms
of gear-related mortality. Much research effort has been directed at estimating mortality rates for salmon that are hooked and then rel ...

Estimating the stock proportions of mixed-stock fishery samples by means of genetic stock identification has played an important role in the management of salmon fisheries. In addition, stock identification of individual ...
